Regular expressions: Match a repeating string

[pastet89]

Hello all!
I have that string:

$str = "blablabla 00 00 bla 11 blablabla 22 blablabla 33 33 33 33 blabla 44 bla";

and I want to get that output from it:

Array
(
    [0] => Array
        (
            [0] => bla 00 00 bla
            [1] => bla 11 bla
            [2] =>  bla 22 bla
            [3] => bla 33 33 33 33 bla
        )

[1] => Array
    (
        [0] => 00 00
        [1] => 11
        [2] => 22
        [3] =>  33 33 33 33 
    )

)

The [0] array is not important for me. I know it always will contain the whole matches. But what I need is in the second array [1], to get all the numbers, REPATING OR NOT. I use that code:

preg_match_all("#" . "bla([[:space:]]*[0-9]{2}[[:space:]]*)*bla" . "#", $str, $ma4);
print_r($ma4);

and what I get is:

Array
(
    [0] => Array
        (
            [0] => blabla
            [1] => bla 00 00 bla
            [2] => blabla
            [3] => bla 22 bla
            [4] => blabla
            [5] => blabla
        )

[1] => Array
    (
        [0] => 
        [1] => 00 
        [2] => 
        [3] =>  22 
        [4] => 
        [5] => 
    )

)

Please, help me to get the code I need!

The pattern I came up with that closest mimics what you seek would be as follows:

Example:

$str = "blablabla 00 00 bla 11 blablabla 22 blablabla 33 33 33 33 blabla 44 bla";
preg_match_all('#bla\s+((?:\d+\s+)+)(?=bla)#i', $str, $matches);;
$matches[1] = array_map('rtrim', $matches[1]); // remove right spaces from array elements
array_pop($matches[1]); // remove the final array element (in this case, 44) from array
echo '<pre>'.print_r($matches[1], true);

Output:

Array
(
    [0] => 00 00
    [1] => 11
    [2] => 22
    [3] => 33 33 33 33
)

Obviously, if you wanted to include that final number 44 array element value, don't include the array_pop line. I also used the i modifier to make it all case insensitive (just incase the blah part is upper or lower case.. if this is not needed, simply remove that modifier.

Thanks a lot...Strange to me, because I am working with regular expressions for a long time, but I can not read your regex code and apply it to my real project! Can you help me with that? Here goes the real project:
String:

td>team1</td>
<td><img src='/img/b.png' class='redYellowCard' alt='' \> team2</td>
<td><img src='/img/b.png' class='redYellowCard' alt='' \> <img src='/img/b.png' class='redCard' alt='' \> team3</td>

Array needed:

   Array
(
    // the whole matches
    [0] => Array
        (
            [0] => team1
            [1] => <img src='/img/b.png' class='redYellowCard' alt='' \> team2
            [2] => <img src='/img/b.png' class='redYellowCard' alt='' \> <img src='/img/b.png' class='redCard' alt='' \> team3 
        ) 
    //the images independently of their number - 0, 1, 2, 3 etc. For the simple expample, I give the maximum of 2 
    [1] => Array
        (
            [0] => 
            [1] => <img src='/img/b.png' class='redYellowCard' alt='' \>
            [2] => <img src='/img/b.png' class='redYellowCard' alt='' \> <img src='/img/b.png' class='redCard' alt='' \>
        )
    //the teams
    [2] => Array
        (
            [0] => team1
            [1] => team2
            [2] => team3
        )

)

I was using that code trying to get it:

preg_match_all(
"#" . "(<[a-z][a-z0-9]*[^<>]*>)" . "([[:space:]]*\<img src='/img/b.png' class\='[redYlowCard]+' alt\='' /\>[[:space:]]*)*" . "([a-z0-9]+)" . "(</[a-z][a-z0-9]*[^<>]*>)"
)

but it was matching MAXIMUM one image!
I would really appreciate if you help me to apply your code to that project.

Have you considered using [man]DOM[/man] to parse the HTML? Then you wouldn't have to parse it yourself.

... I have just fixed it without them!!! 🙂🙂🙂
Thanks a lot for the initial help!!!
Here is my code:

((?:[[:space:]]*<img src='/img/b.png' class\='[redYlowCard]+' alt\='' /\>?[[:space:]]*)*)
